Description

technical field [0001] The invention belongs to the technical field of live detection of capacitive equipment, and in particular relates to a sampling device for the last screen of the live detection of the capacitive equipment, which is a sampling device for the last screen signal of the charged detection of the insulation state of the capacitive equipment. Background technique [0002] In high-voltage electrical equipment, most of the equipment is capacitive insulation equipment. For high-voltage capacitive equipment, through the inspection of its insulation performance, equipment defects that are still in the early development stage can be found. In order to detect the insulation parameters of capacitive equipment, it is generally necessary to extract the leakage current signal of the equipment, that is, the current signal on the grounding wire of the end screen of the equipment. [0003] At present, live detection technology has been widely used in the detection of vari...

AI Technical Summary

Problems solved by technology

However, due to the fact that the end screen of capacitive equipment needs to be reliably grounded during operation, and the grounding point of the end screen is often set high, the safety distance is insufficient, which leads to the inability to carry out the live detection work of the insulation state of capacitive equipment smoothly.

For the insulation state of capacitive equipment, the power sector still adopts the mode of power outage maintenance, which is very inefficient
